We were spending a lot of time figuring out the data side of things instead of focusing on the model. Serideo took a lot of that work off our plate. They understood what we were trying to build, helped us get the right people involved, and made the whole process much easier.

Serideo is excellent for part-time andremote work. The training is compulsorybut very easy, like solving primary-schoolquestions. Annotation tasks are alsosimple, and the Al support saves a lot oftime. I especially appreciate theirpre-labeling Al, it's well-structured andhighly accurate for medical data.
